1 Cells Structure and Function

2 Cell Theory zAll living things are made of cells. zAll cells come from preexisting cells. zThe cell is the basic unit of organization in living things.

3 Two Types of Cells

4 Prokaryote zCells that lack internal structures surrounded by membranes. zCells with no defined nucleus. The DNA is a circular strand.

5 Eukaryote zCells with organelles surrounded by membranes.

6 Animal Cells zkzk zThis is what your animal cells should have looked like! zCan you identify any parts?

7 Plant Cells zThis is what your plant cells should have looked like. zWhat are the green structures?

8 Flip book of cell Organelles Title Page: Parts of a cell First Flap: Boundaries Second Flap: Support and Locomotion Third Flap: Energy Fourth Flap: Assembly & Transport Fifth Flap: Storage Sixth Flap: Control

9 Parts of a cell:

10 Boundries

11 Divide this page into two sections

12 Cell Membrane zSelectively permeable zControls what enters and leaves the cell. zMaintains chemical balance. zDefines the boundary of the cell. zBoth plant and animal cells

13 Cell Wall zGives a firm structure to plant cells. zMade mainly of cellulose. zPlant Cells ONLY

14

15 Divide this page into two sections

16 Cytoplasm zJelly-like substance that supports the organelles. zMany chemical reactions take place in the cytoplasm.

17 Cytoskeleton zSupport zScaffolding in the cytoplasm zMicrotubules & Microfilaments

18

19 Divide this page into two sections

20 Chloroplast zContain pigments that absorb energy needed to run photosynthesis. zFound in plants and some protozoans. zPLANT CELLS ONLY!

21 Mitochondria zProduces energy for the cell through cellular respiration zPlant and Animal Cells!

22

23 Divide this page into two sections

24 Endoplasmic reticulum zSystem of passages that transport substances around the cell. zTwo types: ysmooth yrough (has ribosomes)

25 Ribosomes zProtein synthesis

26 zStorage & Digestion

27 Divide this page into three sections

28 Vacuoles zMembrane bound containers for storage and transport of substances in the cell.

29 Lysosome zVacuole that contains digestive enzymes. zCleaner-upper zAnimal Cells ONLY!!

30 Golgi Apparatus zMembrane sacks that store newly produced proteins. zLike a post office: packages proteins and prepares for shipment

31

32 This page will have one drawing in the middle with four sections surrounding it.

33 Nucleus zControl center for the cell. zContains the information for all cell activities. zHas a double, selectively permeable membrane.

34 Nucleolus zProduces ribosomes

35 Chromatin zLong strands of DNA that hold the directions for all cell activity.

36 Centrioles zInvolved in cell division
